OK, the issue is that query:get_description() should be str(query) - this got changed at some point during development of the Lua bindings, but the examples weren't updated to match.

Fixed in trunk r16805. Needs backporting to the 1.2 branch.

Backported for 1.2.13 in r16825. Thanks for your report.
